I have been getting pretty poor mileage in my brand new used 1995 Non-Turbo 900S. A mechanic suggested changing the oxygen sensor and idle control valve. The sensor looks pretty straightforward, but I don't know where the IC valve is located, or how hard it is to change. Any ideas? Thanks.

 

The idle conrol valve is really easy to do. Usually located on the left side of the throttle body...has a connector and two hoses attached to it. I'll see if I can find a pciture.
